近年来,由于广泛使 用低位发热量≤4000 大卡/公斤、灰分≥ 40%的劣质烟煤、贫煤,以 及在动力锅炉上难以燃烧 的挥发分极低的无烟煤、 高水分褐煤和洗中煤,给 锅炉的安全和经济运行带 来一连串问题。如炉膛温 度低,锅炉出力下降;煤 粉着火困难,常常需要投 用助燃油;煤粉燃烬度

In recent years, due to the widespread use of low calorie ≤ 4000 kcal / kg, ash ≥ 40% of poor quality bituminous coal, lean coal, and hard to burn in the power boiler anthracite low volatile, high moisture lignite and washing coal, Bring a series of problems to the safety and economic operation of the boiler. Such as the furnace temperature is low, the boiler output decreased; coal ignition difficulties, often need to vote to help fuel oil;
